Abstract Surfactant is an important material which has both hydrophilic and hydrophobic functionalities, and widely used in detergents, emulsifiers, foaming agents, and personal cares. Linear alkylbenzene sulfonate (LAS) is the most used surfactant material in household detergents with a 60 % market share. However, this material is made from petroleum-based feedstock and has limited tunable pathways for production, resulting in poor hard water stability. We propose a novel surfactant material (Oleo-furan Sulfonate, OFS) designed with biomass-derived furan and fatty acid by new chemical pathways. Friedel-Crafts acylation is a key chemistry for first C-C bond of furan and fatty acid over the heterogeneous catalyst such as zeolite or the homogeneous catalyst such as trifluoroacetic anhydride. The pathway for this furan-based surfactant is highly tunable, where surfactant functionality can be tuned by using different chain-length fatty acids and combining with other chemistries to make different surfactant structure. This novel surfactant material shows similar performance of detergency, solubility, foaming growth and wetting property with commercial LAS surfactant. Importantly, the OFS surfactant demonstrates a hundred-fold improvement in hard water stability compared with commercial surfactant materials. Thus, this novel material retains the detergency in extreme hard water conditions without the need for chelating agents which is generally included about 20-30 % in conventional detergent product. It could be a promising material for numerous applications regarding on amphiphilic functionality of fluid surface control.
